This is dedicated to Dan Zelph who provides constant encouragement, support and guidance always like a perfect gentlemen.
This is based on the concept that the longer we can keep turbulated exhaust in the space been the windscreen and the pot, the greater the heat extraction.
I call this the JenBar Swirl after my daughter and also my wife. I was young man (not baby sitting as he started beating me at chess at age 3)sitting my 7 year old super jock grandson. I watch him side down the tightly wound McDonald's playland slide and had the lite bulb turn on moment. How don't I make the exhaust swirl around the pot without too much weight addition and with the strength to stay attach permanently to the pot. I am on generation 4 or so and this week I hope to make a real prototype. I have made a number of test beds using wood stove gasket with a coat hanger to make and hold the slide swirls in the proper shape and position and the size/shape of the swirling bends. This gave me the easy ability to test the amount of swirls and the distance between the pot and the wind screen.
A probably will make the first proto type with aluminum flashing. Ultimately will use much lighter tooling foil or titanium. Not being an engineer, I had to cut up a boat load of empty cereal boxes to figure out the template to cut the slide and support tabs. Everything on that is set except for the blood the will be required during the cutting.
The aluminum flashing slide will be high temp epoxied to the pot itself(a Zelph 32 oz flat bottom ridged conquistador)The inner windscreen will be horizontally corrugated for strength since the final version will be very light Next comes a 1/16 to 1/4" of carbon felt or fiberglass insulation (insulation suggestions appreciated) and then a final corrugated tooling foil cover. The windscreen will be as tall as the stove plus clearance plus the file pot height. The temporary packing storage container will be a oatmeal round cardboard container or an old aluminum coffee pot.(packing storage containers appreciated.)
The windscreen may have a permanent bottom for rigidity and possibly swing out feet with holes to use with small stakes.
the width between the inner windscreen and the pot will be approximately 3/4" away from the pot and possibly more depending on many sides I add. Slides mean the exhaust must bend which chokes efficiency so the opening gap must me larger.
THe air inlet holes will be substantial but will be side opening as shown in Zelph's swirling inlets posted here or on his website. A drop of epoxy will help help the side hinged doors from being moved. There will be an inner lower ring of Dan's old style corrugate windscreen that will be somewhat taller than the inlet air holes & this will be epoxied in place. There will be a lip on the bottom of the windscreen that will hold a tooling foil with similar air holes as in the windscreen that can close up or limit the amount of the air inlet flow. The stove is Dan's giant starlyte that cones with his conquistador kit. I will extend the lighting wick so it can reach to an easy place to light. I am considering making the lower portion of the windstand a separate section that the top windscreen will stack onto. The stove will been epoxied to a piece of carbon felt and than to the bottom of the pot. I will have a simmer ring to fit on the top of the Starlyte as well as the ability to turn down the air inlet vents. There will be a base reflector made out of kitchen aluminum to help keep the stove cool.I may want to put a viewing pot so I can monitor the flame.
This is wear I am. Picture will follow if I get it together, up and running.
All suggestions greatly appreciated,
And thanks again to Dan the man.
